Light changes its direction when it passes from one transparent medium into another transparent medium. What is this phenomenon called?
ADispersion of light
BReflection of light
CAbsorption of light
DRefraction of light
Answer & Solution
Correct answer: D. Refraction of light
1. The chapter defines: light changes its direction when going from one transparent medium to another transparent medium.
2. This bending of light at the boundary between two media is named refraction.
3. Reflection is light returning into the same medium; dispersion is splitting into colours; absorption is loss of intensity.
4. Hence the phenomenon is refraction of light.
